Updates for RethinkDB and FreeBSD and a 64-bit .NET JIT boost – Snippets

RethinkDB gets multi-indexing: The developers of the open source, NoSQL database RethinkDB have announced version 1.10 which comes with the ability to index rows with fields of multiple values, like say an list of tags for a blog entry. Looking for all records with a particular tag previously required slow iteration, but now with the multi-index it is possible to index the set of values within the field and then to “get_all” for a particular tag value using that index. RethinkDB server is written in C++ and AGPL licensed with Apache licensed client drivers.

RyuJIT for .NET: Over in the world of .NET, interesting things are afoot with a new 64-bit just-in-time compiler, RyuJIT, making its debut as a CTP (Community Technical Preview). .NET’s had a 64-bit JIT for some time, though the JIT has apparently been quite slow. RyuJIT runs twice as fast and overall gives a 30% speed up to start up. One benchmark with regular expressions went off the scale, going from a 1.4GB working set and 60 seconds run time to 199MB and 1.8 seconds run time – yes the older compiler is particularly bad at regular expressions.
